Reactions of ionised pyridazine, aminopyrazine and aminopyridine and their isomeric alpha-distonic ions

The reactions of ionised pyridazine, aminopyrazine and aminopyridine and the corresponding alpha-distonic ions are examined by a combination of tandem mass spectrometric techniques, including analysis of metastable ion (MI), collision induced dissociation and neutralisation-reionisation mass spectra (NRMS). Further insight into the relative stability and energy barriers towards tautomerism of each ionised heterocycle with its alpha-distonic isomer is obtained by computational methods. In all these systems, both the conventional radical-cation and the alpha-distonic tautomer are stable species which exist in discrete energy wells, with a significant barrier towards their interconversion. Although each alpha-distonic ion is sufficiently stable to survive neutralisation-reionisation, the conventional ionised heterocycle is more stable in each case. The possibility of investigating proton-transport catalysis in the tautomerism of these ionic systems is discussed.

An efficient approach to chiral C8/C9-piperazino-substituted 1,4-benzodiazepin-2-ones as peptidomimetic scaffolds

(Chemical Equation Presented) A promising way to interfere with biological processes is through the modulation of protein-protein interactions by means of small molecules acting as peptidomimetics. The 1,4-benzodiazepine scaffold has been widely reported as a peptide-mimicking, pharmacogenic system. While several synthetic pathways to C6-8 substituted benzodiazepines have been disclosed, few 1,4-benzodiazepines substituted at C9 have been reported. Herein, we describe a versatile approach to introduce cyclic, protonatable functionality at C8/C9. Introduction of the piperazine system at C8 and C9 gave access to a unique functionalization of the versatile benzodiazepine skeleton, broadening tailoring options on the benzofused side of the molecule, and the possibility of discovering novel peptidomimetics potentially able to modulate protein-protein interactions. Coupling of activated amino acids with poorly reactive anilines under mild conditions, while avoiding racemization, gave easy access to these compounds. Efficient amino acid activation was obtained by exploiting the rapid formation of acid chlorides under low temperature and acid/base free conditions, using triphenylphosphine and hexachloroacetone. This procedure successfully resulted in high reaction yields, did not produce racemization (ee > 98%, as demonstrated by using chiral solvating agents), and was compatible with the acid sensitive protecting groups present in the substrates.

Design, synthesis, and biological evaluation of potent and selective class IIa histone deacetylase (HDAC) inhibitors as a potential therapy for huntington’s disease

Inhibition of class IIa histone deacetylase (HDAC) enzymes have been suggested as a therapeutic strategy for a number of diseases, including Huntington’s disease. Catalytic-site small molecule inhibitors of the class IIa HDAC4, -5, -7, and -9 were developed. These trisubstituted diarylcyclopropanehydroxamic acids were designed to exploit a lower pocket that is characteristic for the class IIa HDACs, not present in other HDAC classes. Selected inhibitors were cocrystallized with the catalytic domain of human HDAC4. We describe the first HDAC4 catalytic domain crystal structure in a “closed-loop” form, which in our view represents the biologically relevant conformation. We have demonstrated that these molecules can differentiate class IIa HDACs from class I and class IIb subtypes. They exhibited pharmacokinetic properties that should enable the assessment of their therapeutic benefit in both peripheral and CNS disorders. These selective inhibitors provide a means for evaluating potential efficacy in preclinical models in vivo.

Simple and efficient preparation of (R)- and (S)-enantiomers of alpha-carbon deuterium-labelled alpha-amino acids

A procedure for the synthesis of (R)- and (S)-enantiomers of alpha-carbon deuterium-labelled alpha-amino acids, exemplified for (R)- and (S)-[2-2H1]-Leu is described. Starting from the respective (S)- or (R)-enantiomer or from the racemic mixture of an alpha-amino acid the selective proton exchange at the alpha-carbon is carried out by racemization via a Schiff base in monodeuterated acetic acid as solvent which serves as deuterium source. After N-protection the racemic mixture is liquid chromatographically separated into the individual (R)- and (S)-enantiomers on preparative scale employing a chiral anion exchanger based on carbamoylated quinine as chiral selector. After deprotection the enantiomerically pure products can be obtained in good yields.
